Requirements Analysis, 5. Design, 6. Development, 7. Integration and Test, 8. Implementation, and 9.Operations and Maintenance. Each stage has its own objectives, deliverables, and activities that ensure a systematic and effective approach to system development. References: CITM Course Outline, System Development Life Cycle - GeeksforGeeks, Systems development life cycle - Wikipedia

 Classes are a representation of some real-world thing and a number of specific instances of that thing. Classes define the common characteristics and behaviors of a group of objects, such as properties, methods, and events. Objects are individual instances of classes that can have different values for the properties and variables defined by the class. Procedures are blocks of code that perform a specific task or function. Links are connections between objects that allow communication and interaction. References: Objects and Classes – Programming Fundamentals, Objects and classes - Visual Basic, Object-Oriented Programming: Objects, Classes & Methods

A logic bomb is a type of malicious code that is inserted into a software program and remains dormant until a specific condition or event occurs, such as a certain date, time, or user action. When the condition is met, the logic bomb activates and executes its harmful payload, which can range from deleting or corrupting data, to displaying unwanted messages, to crashing the system. Logic bombs are often used by disgruntled employees or hackers to sabotage an organization’s IT infrastructure or to extort money or information. Logic bombs are different from keyloggers, spam, and viruses, which are explained below:

• A keylogger is a software or hardware device that records every keystroke made by a user on a computer or mobile device, usually for the purpose of stealing passwords, personal information, or other sensitive data. Keyloggers can be installed by hackers through phishing, trojan viruses, or physical access to the device. Keyloggers do not wait for a specific condition to activate, but rather run continuously in the background and transmit the captured data to a remote server or storage device.
• Spam is any kind of unwanted, unsolicited, or irrelevant digital communication that is sent or posted to a large number of recipients or places, typically for the purposes of advertising, phishing, spreading malware, or disrupting normal operations. Spam can be delivered via email,text message, phone call, or social media. Spam does not contain hidden code that executes a harmful action, but rather relies on the user’s response or interaction to achieve its goal, such as clicking a link, opening an attachment, or providing personal information.
• A virus is a type of malware that infects a computer or mobile device by attaching itself to another program or file and replicating itself when the host program or file is executed. A virus can have various harmful effects, such as deleting or modifying data, consuming system resources, displaying unwanted messages, or opening backdoors for hackers. A virus can spread from one device to another through networks, removable media, or email attachments. A virus does not require a specific condition to activate, but rather runs whenever the infected program or file is executed.

Functional design is a design approach that focuses on the functionality and performance of a system, rather than its structure or appearance. Functional design usually begins with specifying the desired output, such as the goals, objectives, and requirements of the system, and then derives the input, processes, and data needed to achieve the output. Functional design can be applied to various types of systems, such as software, hardware, or business processes. Functional design is often contrasted with other design approaches, such as organizational design, object-oriented design, and structured design, which have different emphases and methods. References:

 An Integrated Global IT approach is a strategy that aims to align the IT functions and capabilities of a firm with its global business objectives and needs. One of the benefits of this approach is that it enables the firm to provide more consistent customer service internationally, by leveraging common platforms, standards, processes, and data across different regions and markets. This can enhance customer satisfaction, loyalty, and retention, as well as reduce costs and risks associated with IT fragmentation and duplication. References: Integrated Global IT approach customer service, Toward an integrated technology operating model, Managing Global Customers: An Integrated Approach, Five steps to an integrated customer experience

A transitional strategy is helpful in seeking global efficiency while retaining local responsiveness because it combines the benefits of both standardization and adaptation. A transitional strategy aims to achieve high levels of global integration and local responsiveness by leveraging the interdependence and learning among different units of the organization. A transitional strategy requires a complex and flexible organizational structure, a strong global culture, and effective coordination and communication mechanisms12. References: 1: CITM Study Guide, Chapter 4: Global IT Strategy 2: Balancing Global Synergies and Local Responsiveness | SpringerLink

Rotational delay is the time it takes for the desired sector of the disk to rotate under the read-write head after the head has been positioned at the correct track. It depends on the rotational speed of the disk and the position of the sector relative to the head. It is one of the components of data access delay, along with seek time, transmission delay, and processing delay. References: Delays in Computer Network - GeeksforGeeks, Access time - Wikipedia

Reciprocal interdependence occurs when two organizations depend on each other in a cyclical manner, such that the output of one becomes the input of the other and vice versa. This type of interdependence is the most complex and difficult to manage, as it requires constant coordination and communication between the organizations. An example of reciprocal interdependence is the relationship between a software development company and a software testing company, where each one relies on the feedback and quality of the other’s work. References: Three Types of Interdependence in an Organizational Structure, Interdependence in International Organization and Global Governance

Data warehousing and data mining are closely related technologies that support business intelligence and analytics. Data warehousing is the process of collecting, integrating, and organizing data from various sources into a centralized repository that can support complex queries and analysis. Data mining is the process of applying various techniques and algorithms to extract useful information and patterns from the data stored in the data warehouse. Data mining can help discover hidden relationships, trends, anomalies, and insights that can improve decision making and performance. One of the main reasons for building a data warehouse is to enable data mining, as data warehouses provide a consistent, reliable, and comprehensive source of data that can be mined for various purposes. Data warehouses also facilitate data mining by providing data quality, data cleansing, data transformation, data aggregation, and data indexing services that can enhance the accuracy and efficiency of data mining. Data warehouses and data mining are complementary technologies that work together to deliver business value and competitive advantage. References: Data Warehousing and Data Mining 101, Data Warehousing and Data Mining - Topcoder, Difference between Data Warehousing and Data Mining

Application software is a type of computer program that performs a specific personal, educational, or business function. It is designed to help users perform an activity or solve a problem. Application software can be classified into two basic categories: general-purpose and specific-purpose. General-purpose application software can be used for a variety of tasks, such as word processing, web browsing, or image editing. Specific-purpose application software is tailored for a particular domain, such as accounting, engineering, or gaming12

According to these definitions, Adobe Photoshop, Internet Explorer, and Microsoft Word are examples of application software. Adobe Photoshop is an image editing software that allows users to create and modify digital images. Internet Explorer is a web browser software that enables users to access and view web pages. Microsoft Word is a word processor software that allows users to create and edit text documents. All these software are designed to help users perform specific tasks and are independent of the operating system or hardware.

On the other hand, Linux and Unix are not examples of application software. They are examples of system software, which is a type of computer program that controls and manages the operation of the computer and its peripherals. System software includes operating systems, device drivers, firmware, and utilities. Operating systems, such asLinux and Unix, are system software that provide the basic functions and services for running other software and applications. They are responsible for managing the hardware resources, such as memory, CPU, disk, and network, and providing the user interface, such as command-line or graphical. System software is essential for the functioning of the computer and is usually pre-installed or embedded in the computer123 References: 1: Application software | Definition, Examples, & Facts | Britannica, 2: What is Application Software?
